    A4 and A8 Series Recessed

    A4 and A8 Recessed Electromagnetic Lock

    Recessed Electromagnetic Locks

    The Recessed Electromagnetic Locks operate with holding forces up to 280kg and 580kg. Covering a range of applications these magnets are ideal for situations where the magnet needs to be recessed such as swing and sliding doors. With fixing options including wood, aluminium and steel constructions, the range caters to most needs. The electromagnets are available in both monitored and non monitored models, using hall effect monitoring on some. These Electromagnetic Locks are CSIRO approved for use on fire doors and are characterised by their high qualityand proven reliability in both fire and security applications.

    Key Features

    • Fail-safe: unlocks when power is removed
    • Easy installation: suitable for both new and retrofit usage
    • High holding force: refer to the technical data overleaf
    • Self-alignment: armature plate pivots to accommodate door drop
    • Silent operation: no humming or buzzing
    • Dual voltage: site selectable 12 or 24 Vdc
    • Monitored versions: hall-effect status monitoring available on some models
    • Instantaneous Release: smart electronics on the Recessed Series Electromagnetic Lock eliminate residual magnetism
    • 5 Year ASSA ABLOY Warranty.

    Applications

    • Various sliding door applications

    Standards and Compliance

    • CE Approved
    • RCM Certified

    Specification Statement
    The A4 and A8 Recessed Electromagnetic Lock should be constructed in an aluminium case with heavy duty electromagnet. The range only operates in Fail Safe mode and relies on a secondary lock or battery backup system.The lock needs to be equipped with “smart electronics” that have zero residual magnetism (instantaneous release). This is crucial for correct operation.
